Cross-Platform Mobile App Developer -- 2

@hasitsolutions

Hi, I have experience working with the skills required for this project, including Flutter UI development, API integration, state management, and translating Figma designs into production-ready code. I can take your remaining screens, convert them into responsive layouts, and fully integrate them with your existing REST APIs so users can create, edit, track, and close tasks smoothly on both iOS and Android. I'll follow your design system closely, wire every widget to the correct endpoint, implement stable token handling with background refresh, and write clean unit tests for the data layer. Reusable widgets, proper caching, dio-based network handling, and error management will all be included. Before we proceed, I need a few details: Do you prefer Provider, Riverpod, or Bloc for state management Are the authentication refresh endpoints already documented How many screens remain to be implemented Do you need offline support (task caching when offline) Thanks & Regards Abhishek

Having been a lead developer on multiple projects throughout my career, I am adept at managing the intricate details of apps, from advising on the most suitable tech stack to provide you with scalable architecture, neat UI/UX design, and thorough documentation. What really sets me apart is my familiarity and expertise with integrating third-party APIs into your project. I have successfully worked with a wide range of them including Google, Facebook, PayPal, Stripe, Twitter, and Twilio APIs. Trust and effective communication are fundamental to completing a project smoothly, which is why I believe in daily chat and sharing detailed documents. My dedication can be seen in the fact that I've personally handled more than 150 big projects and have worked with over 20 clients from across the world. In conclusion, hiring me would mean getting not just a tech stack recommendation or a cross-platform developer but someone who truly loves coding and is committed to providing high-quality work on time. Let's 파start this journey together towards delivering an outstanding app experience for both Apple and Android users!

With over 5 years of extensive experience as a Full Stack Developer, I am confident that I can take your mobile app idea and turn it into a fully-functional reality on both the Apple App Store and Google Play. I have had the opportunity to develop and deliver mobile apps similar to yours in nature using various frameworks including React Native and Flutter -- both of which I find strong contenders for a cross-platform project such as yours. What sets me apart is not only my technical proficiency in designing clean UI/UX and building scalable code, but also my ability to provide end-to-end support to my clients. This involves setting up robust back-end services (like authentication, real-time databases, etc.), ensuring smooth deployment (including testflight submissions) and delivering comprehensive documentation so that you are equipped for long-term maintenance or expansion. Communication is key in any project, and my commitment towards it ensures that we'll remain aligned throughout the entire process. I understand how important your idea is to you, hence I approach each project with utmost care and professionalism to deliver nothing less than perfection. So let's connect, discuss your specific project requirements and build something amazing together!

I’ll take your idea from concept to a polished, production-ready mobile app on both the App Store and Google Play. I recommend Flutter for a single high-performance codebase and near-native UX; alternatively Kotlin Multiplatform if you need truly native UI per platform. For backend services I typically use Firebase or Supabase for auth, realtime/sync, push notifications, and analytics—both speed up delivery and scale reliably. What I’ll deliver: • UX-ready screens (refined from your wireframes) and a clean, platform–aware UI. • Scalable, well-documented codebase (MVVM/Clean) with CI, unit tests for critical flows, and feature-flag readiness. • Backend setup: auth, database, push, analytics, and optional serverless functions. • Regular device builds (TestFlight / Internal Play tracks), final signed App Store / Play Store packages, and hands-on submission support. • Post-launch handover: docs, deployment runbook, and 2 weeks support for fixes. Typical timeline: 8–12 weeks for a full MVP depending on scope. I’ve shipped multiple cross-platform apps and will keep communication tight, deliver incremental builds, and ensure you can maintain or extend the product easily. Best regards, Amaan Khan L. (CUBEMOONS PVT.)

Hi, thank you for outlining your requirements. I can take your app from concept to a fully deployed, production-ready mobile application on both the Apple App Store and Google Play. I work end-to-end—including UI/UX, architecture, development, backend setup, testing, and release management—so you do not need multiple vendors. For cross-platform development, I recommend Flutter because it delivers native-level performance, a unified codebase, fast development cycles, and consistent UI across iOS and Android. It is also highly scalable for real-time features, push notifications, authentication, and analytics. What I will deliver • Clean, modern UI/UX aligned with iOS and Android guidelines • A robust, scalable codebase with clear architecture • Backend services (Firebase or custom API), including auth, DB, notifications, analytics • TestFlight, internal testing, and full App Store/Play Store launch support • Complete documentation and post-launch maintenance I will share a detailed project plan and timeline once I review your wireframes and feature priorities. I have shipped multiple cross-platform apps with similar end-to-end scope and can provide examples on request. If this aligns with your expectations, I’d be glad to discuss your wireframes and begin planning the build.
